Sounds like you may have a leaky 6L6 drawing excessive current, or a power supply issue. Check especially the B- supply (bias supply) 123A and the accompanying resistor network (109, 110, 111, 112, 114, 115, 116, etc.) this is also the grid bias for the 6J5. If the bias is wrong, the plate current on that tube will change. Also check speaker field coil, which is part of this network.
